Gas Appliance Standards - A Comprehensive Guide

Understanding Gas Appliance Standards

Did you know that the first gas stove was invented in 1826? But it took another 100 years before gas stoves became dominant throughout the civilised world. In Australia, we originally used man-made “town gas” from the late 1800s onwards, before officially converting to natural gas in 1969. The Australian Gas Institute was formed in 1932 as a scientific body providing its technical expertise to the industry, and the first gas appliance codes were written, with an emphasis on safety. As the industry further evolved, Standards Australia issued their first Australian Standards for gas appliances, culminating in the current AS/NZS 5263​, which ensures product reliability, consumer safety and environmental protection.

What is AS 5263 and Why is it Important?

AS 5263 (also known as AS/NZS 5263​) is the core Standard for gas appliances throughout Australia and New Zealand. This Standard is used for gas appliances across a range of different settings, including commercial, domestic and light industrial. According to Standards Australia, AS/NZS 5263 provides “manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with uniform minimum requirements for the safety, performance and use of gas appliances”.

Compliance with this Standard by manufacturers, suppliers and installers is important because various government regulations are framed around AS/NZS 5263.

Overview of AS/NZS 5263: Standards for Gas Appliances

The AS/NZS 5263 Standard is a collaboration between Standards Australia and Standards New Zealand to harmonise gas appliance regulations across both countries. AS/NZS 5263 has specific provisions for the following categories of gas appliance: all type A* gas appliances, domestic gas cooking appliances, gas fired water heaters for hot water supply and/or central heating, gas space heating appliances, radiant gas heaters, domestic gas refrigerators, indirect gas-fired ducted air heaters, domestic outdoor gas cooking appliances, decorative effect gas appliances, gas laundry dryers, gas direct-fired air heaters, small gas engine-driven appliances, and gas pool heaters.

* Type A gas appliances are domestic and light commercial appliances, such as cooktops, ovens and hot water systems.

Key Sections of AS/NZS 5263.1.7 and AS/NZS 5263.1.1

Both of these Standards focus on the particular Standards for installation, maintenance, and testing of these two types of gas appliances:

• The AS/NZS 5263.1.7 Standard deals with the category of domestic outdoor gas cooking appliances with an energy input not exceeding 200 MJ/h. In Australia, this Standard allows for fuel gases that are natural gas, town gas, liquified petroleum gas and tempered liquified petroleum gas. In New Zealand, the Standard deals with natural gas and general product liquified petroleum gas.
• The AU/NZS 5263.1.1 Standard covers the specific requirements and test methods for domestic gas cooking appliances, including stovettes, hotplates and separate ovens.

AS/NZS 5263.1.7: Testing and Compliance Requirements

Manufacturers and regulators use AS/NZS 5263.1.7, which details the specific requirements and test methods for domestic outdoor gas cooking appliances (barbeques), because it ensures their safety, functionality, and efficiency. This Standard consists of the current best practices and is not an instruction manual. However, it does give consideration to the prevention of fire hazards and explosions, continuity of satisfactory operation, prevention of injury to persons or property, current gas regulations and legislation, as well as any relevant international Standards.

AS/NZS 5263.1.1: Appliance Design and Construction Guidelines

AS/NZS 5263.1.1 covers the design and construction guidelines for domestic gas cooking appliances such as freestanding ovens and gas cooktops. It outlines the key design features and construction methods to comply with this Standard and ensure the safety and durability of each appliance. AS/NZS 5263.1.1 also provides a set of test methods that may be applicable for the assessment of oven cooking performance. It is the responsibility of the manufacturer or distributor to ensure that these appliances conform to statutory and regulatory requirements.

Compliance and Certification Process for Gas Appliances

Compliance and certification to meet AS/NZS 5263 Standards involves both the manufacturer and installer. In the case of the manufacturer, the certification process might vary from state to state, depending upon the legislation. For example, in Victoria, the Gas Safety Act states that Energy Victoria “may accept an appliance or class of appliances” on application. This legislation also states conditions such as “requirements for the testing of the appliance or appliances in accordance with the regulations by a person or body approved by Energy Safe Victoria”.

What does this have to do with AS/NZS 5263? Everything! On its website, Energy Safe states that it “uses Australian Standards as the basis for the assessment of gas appliance safety”. Therefore, there is a definite role for testing laboratories, such as Intertek, in ensuring compliance with Standards like AS/NZS 5263 and the steps manufacturers must take to obtain certification.

The Role of Accredited Testing Laboratories

While specific legislation can vary from state to state, in general, the state agency will authorise a number of accredited testing laboratories to be certification bodies. Submissions for certification must be made directly to one of these certifying bodies. These accredited laboratories will then assess gas appliances, conduct necessary tests, and issue compliance certificates.

Penalties for Non-Compliance with Gas Appliance Standards

Non-compliance with gas appliance Standards can cause violations of state legislation and state agency regulations. Why? Because many states include these Standards in their legislation (either directly or indirectly through their state agencies). As non-compliance leads to increased safety risks, violations of the Standards might result in legal implications or bring about penalties such as fines or imprisonment. These gas appliance Standards outline the current best practices, and adhering to them helps ensure consumer safety and avoids any future issues.

Best Practices for Manufacturers and Suppliers

What are the best practices for manufacturers and suppliers to ensure their gas appliances meet AS/NZS 5263 Standards? Proactive measures work best! These include:

• Regular testing of components and appliances, especially when a component supplier makes a change.
• Staying up-to-date with revisions of the AS/NZS 5263 Standard or any other relevant Standard.
• Collaborating with accredited testing laboratories.

Conclusion: The Importance of Gas Appliance Standards for Safety and Compliance

The AS/NZS 5263 Standard is a collaborative effort between Standards Australia and Standards New Zealand, which outlines the specifications for gas appliances in both countries. Complying with these gas appliance Standards is crucial for customer safety, legal reasons, and consumer confidence. To ensure that you are in full compliance with these Standards, you can consult with experts such as Intertek Inform.
